FRANK A. GAUGER AND ROY W. JOHNSON, 0F MILWAUKEE, WISCONSIN. FLASH IGN ITER.

Specincation of Letters Patent.

Application filed December 6, 1920. Serial No. 428,569.

To @ZZ whom 'it may concem.'

Be it known that we, F RANK A. GAUGER and ROY W. JOHNSON, both citizens of the United States, and residents of Milwaukee, in the county of Milwaukee and State of isconsin, have invented certain new and useful Improvements in Flash I niters; and We do hereby declare that the fo lowing is a full, clear, and exact description thereof.

ur inventionrelates to new and useful improvements in flash igniters for use in connection with the burners of gas stoves and the like, and includes the usual constant burnin pilot light, a cover therefor and a valve igor controlling the flow of gas.

It is one important object of this invention to provide a very simply constructed Hash igmter valve which, because of the fact that it is formed of a fewer number of parts than the usual valve of this character, may

quite inexpensively manufactured.

A further object of the invention is to provide a simple and new arrangement of parts of a valve of this character for providing the necessary continuous limited flow of as for the pilot light.

n additional imnortant object of the in-V vention is to provi e an improved coverin for the torch-head of the device which, while effectively protecting the pilot light, ma be cheaply made from a" single metal blan or from a casting. Y

In further reducing the cost of manufacture, which is one of the fundamental principles of this invention, the torch head is disposed horizontally and mounted directly on the end of the trol valve and forms a support for its protective covering.

With these and other objects in view the invention resides in the novel features of construction, combination and arrangement of parts which will be hereinafter more particularly described and claimed.

In the accompanying drawings Figure 1 represents a vertical sectional view through portions of a flash igniter assembly constructed in accordance with our invention, and

Figure 2 is a plan view of the protective oo vermg or canopy of the tOrch-headi Referring more particularly to the drawsupply pipe from the con- V ing disposed against a packing was ing, it will be seen that the valve `structure of our invention includes a body casting 1 having a normally vertically disposed transversely formed well 2 intermediate its ends, into which ports 3 and 4 enter from said ends. The-inner ends of the ports 3 and 4 commmunicate with the well 2 at points spaced longitudinally thereof, and1 midway between these points the preferably cylindrical wall of the well 2 is provided with an annular shoulder 5 forming a valve seat. The port 4 is adapted to communicate with a main supply pipe, whereas the other port 3 opens into the adJacent end of a branch supply pipe 6, the same being threaded into the O casting 1 and supported thereby.

The upper or outer portion of the wall of the well 2, above the point of entrance of the port 3 thereinto is screwthreaded to receive the intermediately threaded portion of a sleeve plug 7. The inner end portion of the plug 7 has its peripheral surface shaped to provide an annular valve head member 8 for co-operation with the valve ,seat 5. Thus by threading the sleeve plug 7 inwardly or outwardly of the well 2, this portion 8 is varied in its relation to its cooperating valve seat 5. Between said valve head portion 8 and the screw-threads of the sleeve plug 7, the latter is provided with an annular recess 9 which registers with the port 3 and has openings 10 communicating therewith, which o enlngs are formed through the wall of the sleeve plug from the bore thereof.

Movable longitudinally within the bore of the sleeve plug 7 is a valve-stem 11, the same having a valve-head 12 on its inner end for co-operation with the similar end of the sleeve-plug ,as shown in Figure 1. The Outer end of the stem 11 carries a push-button 13, one ortion of which is reduced in diameter andp slides within the sleeve plug 7, this portion also having one end of an expanslble coiled spring 14 dis osed thereagainst for normally ur ing t e button 13 outwardly, the other en of said s ring belier 15 in the bore of the plug 7.

The end of the supply pipe 6 op osite its connection with the bod 1 of t e valve structure has a torch-head7 16 carried thereby, the axis of which torch-head is disposed from the inner end of the horizontally and is coincident with the center line of said supply pipe. Thus the several Hash openings 17 are located in a horizontal plane. Said torch-head 16 is in effect merely a Ytip having an enlarged attaching portion 18 which is threaded over the end of said supply pipe and is also externally screw-threaded for the attachment of a torch-head protective covering or canopy 19.

`In the present instance this canopy is disk-like in shape with slightly downturned edges and is located only a short distance abovethe torch-head 16 so at so protect the same from liquids or other materials which may be dropped into the stove. The canopy is mounted in this. position by an arcuate attaching plate portion 2() which depends from one part of the downturned edge thereof and is provided with a flanged opening, the wall of which opening is screw-threaded for en agement with the attaching portion 18 of t e torch-head'.`

In operation the flash igniter assembly consisting of the parts hereinbefore described is located so that the torch-head 16 will be in a position to permit the simultaneous lighting of several stove burners, if necessary. Owin to the by-pass valve formed within the Well 2 by the valve seat 5 and the valve head portion 8, a limited supply oi. gas is permitted to continuously iow from the port 4to the port 3 and thence by way of the supply pipe 6 to the torch head 16. "When, however, the button 13 is depressed and the valve head 12 moved away sleeve plug 7, a full supply of gas is permitted to enter the supply pipe 6 so that jets ot' liame are projected from each of the several Hash openings 17. Certain of said jets of flame are projected through notches 21 in the opposite side edges of the attaching plate portion 2() of the canopy 19. Upon release of the button 13 the main flow of gas is cut olf and only the pilot iames burn at the torchhead.

We claim:
